Camera History

"The Camera"
1. The camera obscura effect is achieved by when a tiny whole is created in one wall and through the hole light is focused and the outside scene is projected on the opposite wall.
2. In the 17th century Isaac Newton and Christian Huygens perfected the understanding of the optics and also the process of making high quality glass lenses which made them get closer to creating the modern camera.
3. The parts of the first modern camera invented by Niepce were a glass lens, a dark box, and film.
4. Modern digital cameras and niepce's camera have a lens, and film.
5. A digital camera use an electronic sensor called a CCD to capture an image.

"Camera Modes"
6. The difference between the Auto Mode and the Program Mode is that you can actually control flash and few other things on Program Mode not like Auto Mode you can't con toll anything it controls by itself.
7. To attempt to blur out the background, camera will try to use to fastest available lens setting (aperture)
8.The sports mode is used to freeze motion, camera will use the highest shutter speed possible.

"The Half Press."
9. You should do a half press on the trigger button because it will lead to faster camera response time, more control over focus, encourages better composition.

"Controlling flash."
10. This symbol means No Flash.
11. This symbol means Auto-flash

"Introduction to exposure."
12.  The picture will be washed-out if theres is too much light.
13. The picture will be dark if theres not enough light .

"The Universal Stop."
14.  A "stop" is a relative measurement of light.
15.  It is 1 spot brighter in the new planet if there are two suns instead of one.
16.  It is 2 spots brighter in the new planet if there are two suns instead of one.

"Shutters and Aperture."
17. The longer shutter speed the more light there will be.
18. The shorter shutter speed the less light there will be.
19.  The aperture controls the opening known as the F-Spot.
20. The larger the opening the more light will come in.
